Utility and efficient function has made site-to-site VPNs a popular phenomenon in today’s world. They have the ability to connect all networks with each other. For instance, this technology can enable the connection of the network of an organization’s headquarters to its branch office network. In such a system, the hosts have no VPN client software but instead receive or send the TCP/IP traffic via the VPN pathway. This pathway is in turn accountable for encrypting and encapsulating outbound traffic, sending it via the VPN channel over the Internet and then to a VPN pathway at the target location.
Well-established site-to-site VPN connectivity conventionally refers to leased line, frame relay and IPSec operations. Leased line and frame relay connections are extremely secure but expensive at the same time. As a result, IPSec operations are more popular. They help in encryption and allow the internet to set up safe multiple location virtual private networks that are cost effective.
However, along with the advantages, IPSec’s have their share of disadvantages too. For instance, they can only support one encrypted connection. In all other normal deployments, it is essential for two or more sites to be connected to each other. This in turn permits the main applications to correspond, gives business partners admission to a specific set of resources or simply helps in the collaboration of business units. The IPSec’s allow you to achieve the same at the cost of exposing both the network ends.
To aid such a situation, today renowned IT brands are coming up with site-to-site VPN solutions. These solutions use innovative technology and have their advantages too. Some of them are:
- Enables encryption as well as granular access control
- There is site-to-site connectivity and remote access on one platform
- IT overhead and administration are significantly reduced
These site-to-site VPN systems further provide all the function and performance of conventional IPSec connectivity with more benefits. Hence, enterprises needing site-to-site connectivity to facilitate a communication flow between crucial applications can set up long-lasting connections that allow only key servers to communicate. Therefore, there is no threat to security risks and network exposure.
